Specification of Letters Patent.

Patented Oct. 10, 1911.

To all whom it may concern:

Be it known that I, OSCAR L. OWEN, a citizen of the United States of America, and a resident of Whitinsville, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Coiler-Heads, of which the following is a full and concise specification, as required by statute.

The invention is an improvement in coiler heads for cotton drawing frames or similar machines, and its object is to provide an improved protective covering for the coiler gear and its driving pinion, so constructed and arranged that the said parts are effectively shielded from falling dirt or accidental contact by persons when the covering is in place, and can be quickly exposed to unobstructed access by'removing the said covering, either in whole or in part as may be desired and it is a further object to arrange and provide a single coiler gear cover adapted to protect at the same time both the front and back halves of the said coiler gear, being also capable of being readily and bodily removed so as to expose thereby the whole of the gear and hence facilitate its cleansing or removal.

To the above ends the invention involves the construction and arrangement of parts shown and described herein and more particularly defined in the appended claims.

In the drawings, Figure 1 is a horizontal section taken on a plane just below the delivery-rolls of a coiler-head containing the present invention, the parts below the delivery-rolls being shown in plan view with certain portions broken away for clearness. Fig. 2 is a detail plan of the removable coiler-gear cover, separated from the head; Fig. 3 is a vertical section on line IIIIII of Fig. 1 on an enlarged scale; Fig. at is a similar view on line IV-IV of the same figure; and Fig. 5 is a vertical central section of the coiler-head, taken at right-angles to the roller-beam and showing the delivery rolls, their cover and its associated trumpet mechanism.

Referring to the above figures, it will be understood by those familiar in this art that the coiler-head shown, is intended to be fixed or applied to a fixed frame part of a machine which operates upon and delivers a continuous cotton sliver, for instance to the roller-beam of a drawing frame as represented by the drawings, and that it is adapted to receive the continuous sliver from such machine and deposit it in coils in a suitable can or receptacle. The sliver enters the coiler-head through the trumpet 2, by which it is directed into the delivery rollers 3, just beneath it. The latter draw the sliver through the trumpet and deliver it into the mouth of the sliver-tube 4 which forms a part of the revolving coiler-gear 5. This tube is formed by an inclined bore in the body of the gear extending from a central upper point thereof, to a lower point near its circumference, so that as the gear is revolved, the sliver passing down through the tube is thereby laid in continuous coils in the sliver can 6. The coiler-gear is rimjournaled, as shown at 5*, upon the margin of a circular hole in the horizontal coilergear plate 7, and the latter is mounted in projecting relation from the roller-beam, as for instance by means of two end flanges 7 which are integrally formed on the plate and securely bolted to the front face of the roller-beam (see Fig. 1). The plate is formed with two upright side-rims 7 b which extend forwardly from the roller-beam, that is to say, from the attachment flanges 7 with which they are preferably integral, to a point adjacent the opposite sides of the coiler gear, where they are beveled off, to the plane of the plate as indicated by the dotted lines of Fig. 5. These side-rims serve the purpose of strengthening the coiler-gear plate, since they are marginal flanges thereof, and they also operate to close in and protect the coiler-gear at its sides, and for this latter purpose they are made to cooperate with the removable cover 8 of the coilergear. The said cover is shown in plan view separated from the head in Fig. 2. It is formed with an upright front wall 8 surmounted by a semi-conical roof 8, both roof and wall being shaped to inclose the front half of the coiler-gear. The front wall 8* extends circularly around to the opposite sides of the gear somewhat more than 180, where its ends meet or overlap respectively with the forward ends of the side rims 7 being preferably between the rims and the gear thus completing the side closure of said gear.

The conical roof 8 is truncated and open at its top, forming a semi-circular rim adapted to surround the boss of the coilergear which forms the mouth of the slivertube 4, and is provided with two rearwardly extending portions 8 on each side of the rim, which overhang beyond the ends of the front wall 8 and over the rear half of the coiler-gear 5. These extensions provide between them an open space or slot, preferably a parallel-sided slot, of suflicient width toaccommodate the tube-mouth, so that the cover may be slid'over and withdrawn from the coiler-gear in obvious manner. WVhen resting on the horizontal plate, as shown in the drawings, the weight of the front wall and the main semi-conical part of the roof is sufficient to counterbalance the weight of the overhanging extensions 8 so as thus to maintain the cover with adequate stability in an upright position on the plate and with its overhanging portions held safely out of contact with the revolving coiler gear. In its normal or closed position the cover 8 rests in a circular counter-sink 9 formed in the top surface of the coiler gear plate and in such position its interior rim surrounds the tube mouth rather closely, but without touching it. The pinion 10 which drives the coiler-gear is disposed in the space back of it and between the side-rims 7 being itself journaled on a stud 11 and driven through the beveled pinions 12 on the horizontal drive-shaft 13, but the said pinion may be driven in other suitable ways according to the construction of the machine. In the case of drawing frames it is preferred to locate the drive-shaft 13 above the coiler-gear plate as in the example taken for illustration. The space in which the pinion 10 is located is inclosed, and the pinion protected, by a shield 14 which spans the side-rims and extends front and back from the roller-beam to the rear margin of the coiler gear, its front edge being preferably formed on the arc of a circle and underlapping the rearward overhangs 8 of the removable cover. Inthis position the front edge overhangs the rim of the coiler gear. The shield and cover form together a protecting shelter for the gear and its 7 pinion which is continuous, except for the tube-mouth slot, from the roller-beam to the outer side of the coiler-head.

The shield 14 may be supported in place in various ways, but it is preferred to restit removably upon the tops of two hollow fillet blocks marked 7 and appearing in Figs. 1 and 4. These blocks are formed on the coiler-gear plate adjacent the side-rims, but are of less height than the latter so that the shield may rest upon them and between the rims as clearly indicated by the detailed section of Fig. 4. It is thus held against lateral displacement. To permit its re moval it is provided with a slot 15 which accommodates the stud-shaft 11, when the drive-shaft 13 is disposed as shown above the plate. WVhen this shaft is below the plate the slot in the shield may be omitted.

The bracket 16 which supports the usual top cover of the delivery rolls 3, is centrally located on the roller-beam, with re spect to the coiler head, so that it extends forwardly into the open tube mouth slot of the cover and either of itself or by means of attached parts with which it is provided, form a closure thereto, thus completing the shelter of the coiler-gear and its driving pinion. In the form of head taken for illustration the said top-cover bracket extends part way into the tube mouth slot and is provided with a small extension 17 bolted to its end and extending the rest of the way. The bracket 16 is desirably located under the drive shaft 13 and hence so that it projects into or partway into the tube mouth slot, and its width is, therefore, suited to the slot so as to fit the same more or less closely, but the width of the small extension 17 is not thus limited and may overlap the tube mouth slot if desired to make a more complete closure for the gear. Ordinarily such arrangement will not be necessary, and in the drawings the said extension is illustrated as within and substantially filling the slot. The forward end of the extension approaches close to but without touching the top of the sliver tubelmouth, and with the semi-circular opening in the coiler gear cover, forms practically a continuous circular opening within which the tube mouth may revolve. In setting ithe removable coiler-gear cover in place, its jtube mouth slot is guided over the tube lmouth and the cover is pushed back until the ends of its front wall 8 strike the exttreme forward ends of the shield-plate 1 1, 'ithereby pushing that plate back to its proper jposition, in which position the shield forms lan abutment, limiting the inward move iment of the cover and holding the same from contact with the tube mouth boss, the cover itself being held against accidental lateral movement by the engagement of its front wall 8 with the countersink 9 above described or with any other equivalent, abutment means serving the same purpose. Although the shield plate is removable as above described, it is thus locked in place by the cover and can only be removed when the latter has been lifted from its countersink or abutment means. On the removal of the cover, however, the shield may be easily grasped by the hand and removed, thus fully exposing all of the driving mechanism of the head. hen the coiler gear is driven by a drive-shaft located above it, such as the drive-shaft 13, this latter shaft is protected by a curved shield 18 extending from the roller-beam to the top cover 19 of the delivery rolls, thus also sheltering the slot 15, formed in the shield plate 14: to accommodate its removal from the stud shaft 11. The shield 18 is likewise removable and it will be observed that the entire protection of the coiler mechanism is accomplished in part by fixed members of the machine frame, for instance the top cover bracket 16, and in part by cover members which though normally safely confined in position, are yet easily removed.
